Repair of crane wheel by welding
Jireš, Daniel ; Kubíček, Jaroslav (referee) ; Daněk, Ladislav (advisor)
Diploma thesis examines the most appropriate solution of filler materials, suitable technology and welding parameters for the renovation of the crane wheel. Five different filler materials were suggested and have been subject of macroscopic examination and measurement of quality - primary the hardness of the weld deposit. Additional materials have been chosen to design a mobile weld system, which does not count with the possibility of preheating the base material. As the most suitable filler material, which satisfy all the requirements that emerged STEIN-MEGAFIL A 740 M.

Comparison of hand and orbital welding by TIG method
Dušek, Vojtěch ; Hála, Michal (referee) ; Kubíček, Jaroslav (advisor)
DUŠEK VOJTĚCH: Comparison of hand and orbital welding by TIG method This bachelor thesis presents a comparison of manual and orbital TIG welding. It describes the advantages and disadvantages of manual and orbital TIG welding. Mechanical properties, surface structure and heat input on the weld samples were experimentally compared. Thesis also includes technical-economic comparison of these two methods of welding.

Filler materials for the fusion welding
Durajová, Věra ; Kovář, Petr (referee) ; Daněk, Ladislav (advisor)
The bachelor´s thesis elaborated in frame of bachelors studies branch B2341 deals the problematic filler material for fusion welding. On the basis belles - lettres problems technology welding and their filler material was shown it several kinds filler material for individual welding technology (MIG/MAG, hand arc welding, TIG, submerged-melt welding). First is mentioned problems rise fusing watering - place and on what principle individual technology work. After it are mentioned filler material (producer ESAB Vamberk) electrode, tubule, soft - centred tubule.

Industrial robot application in area welding technology
Kozubík, Jiří ; Matějka, Petr (referee) ; Knoflíček, Radek (advisor)
This Bachelor’s thesis, which was written during my studies at the Faculty of Mechanical Engineering, Brno University of Technology, investigates Industrial robot application in area welding technology and is divided into three main parts. In the first is the classification and sorting of industrial robots and manipulators according to different criteria explored. The next part concentrates on industrial robots and manipulators used in current industry and informs of the most important industries for industrial robots. The third and final part deals with welding technologies that are used in robot welding applications, presents a survey on compact welding systems including their description and gives us examples of these cells used at present time.
